I do not own a business but because i sell items through ebay, I have received 1099-k. I was viewed as a business.I purchased business turbotax, Now Do I qualify for QBI?

I figured as they viewed me as a business because i making money through ebay. I then figured i was self employed and purchased business turbotax so i can put down my expenses etc.  Last year turbotax specialist told me to get business version.  So this year I did.  

Am I considered self employed?

Do I qualify For QBI (qualified business income)?

HELP?
